At a glance, I am observing that this file controls the rendering priority of both vector textures and autogens. It’s too dense, so I ask someone who has had any contact with it, if modifying the rendering priorities could theoretically help improve overall performance and fps:
[VTPLayerRenderPriorities]
0=81000 // water 0
1=81010 // water 1
2=81020 // water 2
3=81030 // water 3
4=51000 // streams and power lines
5=102000 // unpaved roads and railroads
6=102100 // paved roads
7=30000 // airport skirtings and parks
8=90000 // shorelines
9=30009 // general (priority = 30000 + layer)
// Vector Textures
//
// Name=human readable name
// Color=AARRGGBB (Microsoft internal use only)
// guid={xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} unique identifier of vector type
// LegacyId=FS9 vector identifier (optional, for backwards compatibility)
// Textures=name or names of textures to apply to this type of vector feature (see order notes below)
// Layout=TILED (for polygons)
// Layout=3_PLUS_1 or 3_PLUS_4 or 7_PLUS_4 (for lines)
// StripWidthMeters=width of line strip in meters
// Size=size of line pixels in meters (for FS9 backwards compatibility only)
// FlattenMode=none or flat or offset or slope
// FlattenOffsetMeters=used when FlattenMode=offset
// FlattenPriority=higher numbers win over lower numbers
// LandClassRemapType=none or cultural or airport or natural or utility
// RenderPriority=higher numbers win over lower numbers
// RenderToTexture=0 or 1
// Water=0 or 1
// VectorAutogen=GUID of vector autogen to apply to line
// ExcludeAutogen=0 or 1
// Effect=name of visual effect file to apply to line
// texture order = wi,hw,sp,su,fa,lm
// wi = mild winter
// hw = hard winter
// sp = spring
// su = summer
// fa = fall/autumn
// lm = light map (night)
Example:
// Stream Lines - stream lines / unknown / perennial
[Texture.0]
Name=Stream_Lines_Perennial

Thank you.
